Display screen with an animated graphical user interface



FIG. 1 is a first image in a sequence for a display screen with an animated graphical user interface;

FIG. 2 is a second image thereof; and,

FIG. 3 is a third image thereof.

The broken line showing of the outermost rectangle and finger in the figures depicts environmental subject matter. The remaining evenly spaced broken lines illustrate portions of the graphical user interface and the dotted lines illustrate text. The broken and dotted lines form no part of the claimed design.

The appearance of the transitional image sequentially transitions between the images shown in FIGS. 1-3. The process or period in which one image transitions to another forms no part of the claimed design. 

CLAIM I claim the ornamental design for a display screen with an animated graphical user interface, as shown and described.
